[0028] The following describes an automatic carton sealing machine according to an embodiment of the present utility model with reference to the drawings.

[0029] Refer to Figure 1 , and the present utility model aims to provide an embodiment of an automatic carton sealing machine.

[0030] An automatic carton 120 sealing machine according to an embodiment of the present utility model includes a conveying mechanism, a carton loading mechanism and a sealing mechanism.

[0031] Among them, the conveying mechanism includes a conveying chain 100 and a first motor 110 that drives the conveying chain 100 to convey. The conveying chain 100 is used to convey the carton 120.

[0032] It should be noted that a pallet is provided inside the conveying chain 100, and the pallet is used to support the conveying chain 100, which can prevent the conveying chain 100 from sagging.

[0033] In some embodiments of the present utility model, a conveying roller 280 is provided at the discharge end of the conveying chain 100. There are several conveying rollers 280, and the several conveying rollers 280 are used to convey the carton 120.

[0034] Thus, after the carton 120 is sealed with glue, the conveying chain 100 conveys the carton 120 to the conveying roller 280, and the conveying roller 280 conveys the carton 120 to the next process.

[0035] It can be understood that a manipulator can be used to transfer the carton 120 from the conveying chain 100 to the conveying roller 280.

[0036] Among them, there are multiple box-carrying mechanisms, and the multiple box-carrying mechanisms are distributed along the conveying direction of the conveying chain 100. The box-carrying mechanism includes two brackets 130 connected to the conveying chain 100. The two brackets 130 are arranged oppositely, and a positioning groove 140 is formed between the two brackets 130. The positioning groove 140 accommodates the carton 120.

[0037] In some embodiments of the present invention, the bracket 130 includes a support shaft 160 and two support plates 170 arranged on the radial outer surface of the support shaft 160. The two support plates 170 are distributed along the axial direction of the support shaft 160, and the support plates 170 are used to support the carton 120.

[0038] Therefore, the structure of the bracket 130 is simple and easy to manufacture, greatly reducing the manufacturing cost of the bracket 130.

[0039] In some embodiments of the present invention, the support plate 170 is connected with a right-angle limit strip 180, and the limit strip 180 matches the edges and corners of the carton 120.

[0040] Therefore, the right-angle limit strip 180 can be used to limit the horizontal position of the carton 120, ensuring that the gluing assembly can accurately glue the two flaps of the carton 120. Moreover, the limit strip 180 can enable the carton 120 to overcome the acting force of the gluing mechanism during the gluing process, avoiding the phenomenon of slipping when the traditional conveyor belt is used to convey the carton 120.

[0041] In some embodiments of the present invention, referring to Figure 4 , the support plate 170 is connected with a sliding sleeve 190. The sliding sleeve 190 is sleeved on the support shaft 160, and the sliding sleeve 190 is provided with a locking bolt 200. The end of the locking bolt 200 abuts against the radial outer surface of the support shaft 160.

[0042] Therefore, the locking bolt 200 can be loosened, so that the sliding sleeve 190 can slide on the support shaft 160. Thus, the relative position of the two support plates 170 can be adjusted, enabling the bracket 130 to adapt to loading cartons 120 of different specifications.

[0043] Among them, the gluing mechanism includes a tape reel 150, a gluing assembly and a cutting assembly. The tape reel 150 is sleeved with a tape roll. The gluing assembly is used to stick the tape on the carton 120, and the cutting assembly cuts the tape.

[0044] In some embodiments of the present invention, referring toFigure 2 The taping assembly includes a taping wheel 210 and a clamping wheel 220 located in the tape feeding direction of the unwinding reel 150. The taping wheel 210 and the clamping wheel 220 clamp and convey the tape.

[0045] Therefore, the unwinding reel 150 unwinds the tape roll, and the taping wheel 210 and the clamping wheel 220 clamp and convey the tape to position the tape, preparing for taping. At the same time, the taping wheel 210 can attach the adhesive surface of the tape to the carton 120.

[0046] In some embodiments of the present invention, the cutting assembly includes a cutter 230 and a first cylinder 240 for driving the cutter 230 to move up and down. The cutter 230 is disposed close to the taping wheel 210 and is used to cut the tape.

[0047] Therefore, the first cylinder 240 drives the cutter 230 to descend to cut the tape on the carton 120 after sealing.

[0048] In some embodiments of the present invention, referring to Figure 3 The cutter 230 has a blade, and the blade is provided with sawteeth 250. Thus, the sawteeth 250 are used to cut the tape, which helps the cutter 230 cut the tape more easily.

[0049] In some embodiments of the present invention, referring to Figure 2 The sealing mechanism further includes a pressing-down assembly. The pressing-down assembly includes a pressing wheel 260 and a second cylinder 270 for driving the pressing wheel 260 to press down. The pressing wheel 260 is used to roll and press the tape on the carton 120.

[0050] Therefore, on the one hand, the second cylinder 270 drives the pressing wheel 260 to press tightly on the top of the carton 120, making the conveying chain 100 convey the carton 120 more smoothly. On the other hand, the pressing wheel 260 can roll and press the tape on the carton 120 to make the tape closely adhere to the carton 120.

[0051] Therefore, the present invention has the following effects:

[0052] First, place the carton 120 on the two brackets 130, and use the motor to drive the conveying chain 100 to convey, so that the carton 120 on the brackets 130 is conveyed to the sealing position. Moreover, a positioning groove 140 is formed between the two brackets 130, and the positioning groove 140 can limit the horizontal position of the carton 120 to ensure that the taping assembly can accurately tape the two flaps of the carton 120.

[0053] Next, the reel 150 is released to feed the tape roll, and the tape adhering wheel 210 and the clamping wheel 220 clamp and convey the tape. At the same time, the tape adhering wheel 210 can attach the adhering surface of the tape to the carton 120. The second cylinder 270 is used to drive the pressing wheel 260 to press the top of the carton 120, and the pressing wheel 260 can roll the tape on the carton 120 to make the tape closely adhere to the carton 120.

[0054] Finally, the first cylinder 240 is used to drive the cutter 230 to descend to cut the tape on the carton 120 after sealing. After the carton 120 is sealed, the conveying chain 100 conveys the carton 120 to the conveying roller 280, and the conveying roller 280 conveys the carton 120 to the next process.

[0055] In the description of this specification, the description with reference to the terms "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0056] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
